I work with computers a lot and personally I hate Acers. They are absolute crap in terms of reliability and workmanship and I really don't like dealing with them. I'd encourage you to look into a different brand, a little extra money will easily save you a lot of trouble.
That said, the only difference between these two that I can see is the Widescreen feature. Some people like widescreen notebooks, some don't (I can go either way). If you like having widescreen (generally better for movies and games) then the choice is clear. Other than that, I can't really see any difference.

hmm i wonder could anyone maybe help me out picking a laptop then cuz i think the acer is like the best i could get on my budget. the laptop would have to be under $750 including shipping and it would have to be off of newegg.com becouse i got a gift certificate for them of $750..
